Requirements
  • Bachelor’s degree in Electrical Engineering, Control Systems Engineering, or a related field.
  • 5+ years in designing and analyzing electrical and/or instrumentation systems, ideally in nuclear, aerospace, energy, or industrial automation.
  • Familiarity with electrical requirements for regulated environments, including wiring codes, control logic documentation, and safety classification.
Responsibilities
  • Own the electrical system level architecture of our testbed and space nuclear reactors.
  • Design and assess electronics and control systems for harsh environments (e.g., space, nuclear).
  • Lead integration, bring-up, and troubleshooting across hardware, firmware, and test infrastructure.
  • Produce and review controlled technical documentation (schematics/wiring, safety inputs, hazard/FMEA-style analyses, test procedures/reports).
  • Evaluate multi-OS or embedded control environments for real-time signal acquisition, ensuring minimal downtime or interference.
  • Coordinate with regulators regarding design basis for instrumentation loops, including fail-safe architecture or redundancy.
  • Own the relevant Documented Safety Analysis (DSA) inputs that address electrical system hazards or potential single-point failures.
  • Participate in each formal design review cycle, ensuring electrical/I&C sections are complete, accurate, and documented.
  • Support the hazard analysis process, identifying possible electrical or instrumentation failure modes and how they’re mitigated.
  • Verify that the final design meets or exceeds relevant standards for safety-class or safety-significant equipment.
Desired Qualifications
  • Master’s degree or higher in Electrical/Controls Engineering.
  • Experience designing and employing electrical systems in space and/or nuclear radiation environments.
  • Understanding of electronic component/system testing for space environments (vacuum, radiation, etc.), and relevant MIL and NASA/ESA standards.
  • Prior experience in nuclear or defense sectors with knowledge of relevant I&C codes (IEEE 379, IEEE 497, etc.).
  • Working knowledge of GDE-987 design review steps and DOE-1189 hazards classification.
  • Experience with advanced control system architecture or SCADA in high-reliability contexts (aviation, nuclear, or automotive safety).
  • Strong communication skills to explain complex control loops and design rationales to both engineers and regulators.
  • Flexibility to support hardware development milestones—including occasional weekend or long-hour pushes.
  • Willingness to travel for test campaigns or supplier engagement, as needed.

What believers are saying

  • Raised $96M Series B in December 2025 to fund R1 factory and fuel fabrication.
  • Selected for USAF JBSA microreactor deployment targeting 2028 operations.
  • First to receive DOE approval for demonstration before July 4, 2026.

What critics are saying

  • X-energy's Xe-Mobile secures DoD contracts with faster licensing by mid-2027.
  • Deep Fission's exclusive HALEU delays Antares fuel, missing 2027 demo.
  • Idaho National Lab delays past July 2026 trigger sodium heat pipe failures.

What makes Antares Nuclear unique

  • Antares R1 uses TRISO fuel and sodium heat pipes for passive cooling in austere environments.
  • Tungsten and boron carbide shielding enables transport in standard shipping containers.
  • Graphite core with boron carbide drums adapts terrestrial design for space missions.

Antares Raises $96M for Microreactor Development for Diverse Energy Applications

Antares raises $96M for microreactor development for diverse Energy applications. News summary. Antares, a nuclear startup, has successfully raised $96 million in a Series B funding round to advance its small modular reactor design, known as the R1 microreactor. This funding includes $71 million in equity and $25 million in debt, with participation from Shine Capital, Alt Capital, Caffeinated, FiftyThree Stations, and Industrious. The R1 microreactor is designed for commercial, defense, and space-based applications, producing between 100 kilowatts and 1 megawatt of electricity using TRISO fuel. The startup's progress follows a renewed interest in nuclear power, evidenced by significant investments in similar companies like X-energy, Deep Fission, Aalo Atomics, and TerraPower. Antares aims to demonstrate its reactor for the Department of Energy next year, with plans to activate its full-power reactor by 2027. Story coverage.

Antares Raises $96M in Series B Funding

Antares raises $96M in Series B funding. Antares, a Torrence, CA-based nuclear energy startup, raised $96M in Series B funding. The round was led by Shine Capital, with participation from Alt Capital, Caffeinated, FiftyThree Stations, Industrious, and other investors, bringing its total amount to date to over $130M in funding. It consisted of $71M in new equity capital and $25M in debt for equipment, factory build-out, and uranium procurement. Led by CEO Jordan Bramble, Antares is building compact nuclear microreactors to deliver energy where it's needed most: * remote military bases, * austere industrial sites, * and, one day, deep space and underwater missions. With operations in Torrance, California; Idaho Falls, Idaho; and Aiken, South Carolina, and a team of 60, Antares is working to demonstrate a low-power test reactor before July 4, 2026, and to test its electricity-producing demonstration unit in 2027. Production units will be deployed as early as 2028.
